*Be it known that I, FRANK Reuse, cit zen of the United States, residing at 'Minneapo- 7 lie, in the county of'Hennepin'and State of Minnesota, have invented certain new and useful Improvements in 'S'creensfor Swinging Sash; and I do hereby declarejthe following to be a full, clear, andex'act description of the inventiomsnch as will enable others skilled the art towhich it appert'ains to make and use" the same. I

My invention has for its ob ect to provide an improved device or'means for mounting the screen of a window sash. j M

Particularly, the invention relates ,to a metallic sash mounted 'for pivotal movements in a steelframe work,for the purpose of ventilating a building. a i The invention is illustrated in the accompanying drawings, wherein like characters indicate like parts throughout the several views. Referring to the drawings Figure 1 isa fragmentary view in jelevation' looking at thesashand' frame structure from the exterior'of the building, some partsbeing broken away and some parts.

, being removed;

I J Fig. 2 "is a view l okingattne sash and frame work from the inner; S1Clo ofthe building, some partsbeing broken away and some parts being removed; a

Fig. 3 is a vertical section taken on the line 3 30f Figs." 1 and2,'some parts being broken away; and'lii, 4 is a view corresponding to 3, with the exceptionYthat the window-see is open.

The frame work in which. the window sash is mounted, is formed by vertical memfbers 4 and horizontal members '5.

frame 6 of the windowsash at its vertical lower panes. v V I p I,

with a rigidly secured thin sheet metal The blade 10, "that projects into close contact with the upper pane.

The window-sash 6 in linewith the ends of the cross bar7,*is pivotallyconnected to the vertical members 4' of the frame work at 11, and the said window sash is thus mounted so that when swung on said pivots from a closed to an open position, its lower portion will moveoutward andits upper portion will move inward. The flange weathering bar 12 1s rigidly secured to the upper muntin "5 and its outer flange overlaps theupper portion of the window sash 6. The upper 'portion'of said windowsashfi is provided with an outwardly extended joint flange 13 'thatoverlaps the inner edge of the weathering bar 12. At its lower portion said window sash 6 is provided with a depending joint "flange 14 that overlaps the outer portion of the lower muntin 5. The numeral 15 nd cates the two-part metal screen frame which, asshown, is (letachablybut rigidly secured in a position by means of turn-buttons 16 applied to the interior Weathering bars and byheaded studs 17 applied to a supplemental bar 18 which,'as shown, is secured to the lower muntin 5. The upper "flange section of the screen frame 15 is provided with a joint-plate 19, the upper edge of which, is shownas bent over to form a rounded surfacethat has contact with the angle iron crossbar 7 approximately in line with the projected axes of the pivots 11,

but so far as this invention is concerned, this frame 15 may be of any suitable construction, When the window sash is moved on pivots 11 from its closed into an open position, the bar 7 being at the axis of the pivot, serves as a pivot bar to maintain contact with the jointplate 190i the lower screen 15, and the screen wire cloth 15 will cover the'space opened by the lower portion of the window sash. The space opened by the; upper portion of the window sash is i kept covered by screen wire cloth 2O held in a rectangular frame 20 which is preferably'of's'ubstantially the same type as the screenframe 15. The said screen frame 20, as shown, and preferably, is made up of two angleiron frame sections having their inner flanges telesooped' and rigidly connected together and to the screen 20. Said frame is ssj therefore formedwith an annular channel 'that is 0 en at sides, bottom and top. The

sides of t e frameQO work'loose'lybut in quite close engagement-with the inner surfaces of a pair 0 laterally spaced upright side plates 21, "which by brackets 22 a are secured to the 'up'rightframe members'4. The inner face of the upper portion of the screen frame 20 rests against the depending outer flange of the weathering bar 12. Studs or guide pins 23 that project inward from the upper portions of the side plates 21, work in channeled sides of the screen frame and guide the upper portion thereof, vertically, while permitting the same to slide and to swing at its lower portion. The lower edge of the screen frame 20 rests on a lower joint plate 24 that is serured to the muntin 9 of the window sash (5 and proje ts outward therefrom and terminates preferably in a turnbead 25. This bead 25 is positioned in the channelof the lower portion of the screen frame 20' and is loosely connected to the inner flange of said frame by a small screw or pin 26 that permits a slightly turning movement of the bead within the channel of said frame 20.

\Vhen the window sash 6 is moved piv otally from its closed to its open position, the beaded edge of the joint plate 24, and consequently the lower edge of the screen frame 20, will be given an outward and slightly upward movement on the arc of a circle, center of which is at the axis of pivot T; and under such movement the screen frame 20 will be raised bodily and given an outward oscillatory movement on the guide pins 23 which latter act as pivots and permit sliding movements of the said screen frame 20. Under all such movements of the screen frame 20, the side plates 21 keep closed the space between the vertical side and edges of said frame 20 and the corresponding sides of the frame work. The screen frame 20 is gravity seated and held on the joint plate 24, but its seating thereon under all conditions, is insured by the screw or pin 26. It is ther fore obvious that he adjustable outer screen will automatically adapt itself to all positions of the window sash. and is also evident that this adjustable screen may be very quickly and easily applied, and while highly e'l'licient for the purposes had in view, is of simple construction and of relatively low cost.

.Vhat I claim is: a a

l. The combination with a frame work and a window mounted therein on inte'rme diately located pivots, of a screen seated at its lower edge on a bar carried by said sash at a point offset from its pivot, the said screen at its upper portion being seated against the upper portion of said frame work for pivotally sliding movements.

2. The combination with a frame work and a window sash mounted therein onin tormediately located pivots, of a screen seated at its lower edge on a bar carried by said sash at a pointoffset from its pivot, the said screen-at its upper portion being seated against the upper portion of said frame work for pivotally sliding movements, and

means closing the spaces between the sides of said screen and sides of said frame work.

The combination with a frame work and awindow sash mounted therein on intermediately located pivots, of a screen seated at its lower edge on a bar carried by said sash at a point offset from its pivot, the said screen at its upper portion being seated against the upper portion of said frame work for pivotally sliding movements, means closing the spaces between the sides of said screen and sides of said frame work, and a lower screen relatively fixed to said frame work and contacting with a portion of said window sash approximately at the axis of its pivot.

4%. The combination with a frame work and a window sash pivotally connected thereto at its intermediate portion by pivots located inward of said sash, said sash having a cross bar approximately at the axis of its pivot, of a relatively fixed lower screen applied to the inner side of said frame work and havin joint flange con tacting with the axial cross bar of said sash, said sash having a lower joint plate projected outward therefrom, an outer screen having a frame seated on said lower joint plate, means guiding the upper portion of the frame of said outer screen for sliding in pivotal movements in close engagement with theupper portion of said frame, and side plates secured to the sides of said frame work and embracing thesides of the frame of said outer screen in all positions thereof.

The combination with a frame work and a relatively fixed lower screen, of a swinging window sash, of an inside pivot structure having means securing the same to intermediate portion of said window sash including a recessed cross bar and a filler strip extending from said bar to the glass of the window sash, said screen having a projecting flange engaging'the recess of said cross bar approximately at the axis of oscillation of said pivot structure.

6. The combination with a frame work and a window sash mounted therein on in termediately located pivots, of a screen which at its lower edge is hingedly connected to the intermediate portion of said sash at points offset from the sash pivot and at its upper edge is connected to the upper portion of said frame for a combined pivotal and sliding movement. a
